This issue appears only if the first login is done from inside a map.

Step to reproduce:

• Open MapStore2 homepage (do no login) -> a list of maps is displayed
• Open a map -> the map opens
• Login -> the map is still open, the User button is green
• Click on Home button -> Home page is visible, "New map" button is visible
• Click on "New Map" button -> the map page opens but the background never loads

I noticed that the url contains "/viewer/openlayers/new" even if Leaflet was selected in the home page
